Thanks for the replies.
We have a ZenNoh ZL1500 which of course is a Kubota (L75...If I recall...I'm in the office doing my day job at the mo..so haven't got my Farming head on).
See the
http://www.orangetractortalks.com/ website for a history of the ZenNoh - Kubota thing.
I managed to get a workshop manual from the US (eBay ...again) and that has helped alot. I have a dodgy alternator also, although I haven't looked at it properly yet, just won't charge the battery. Maybe the usual diodes or brushes inside the alternator. Easy enough to fix.
(The manual covers quite a range of Kubota's smaller tractors L75 and so on) so if anyone wants me to look something up or scan a few pages & email over, that's fine. Just let me know).
If you have one of these grey import Kubota's dressed up as a ZenNoh, then don't mention that to a Kubota dealership, they'll refuse to serve you. There's a chap who can supply almost anything for Kubota's, particularly the ones Smallholders buy (ie little 2 Wheel drive 20 - 30 hp things) and is quite knowledgeable about them as well. Good prices on spares & fast service. I'll dig out his email address & Website URL and post it here.
I fitted a roll bar to mine. 3 years ago I got quoted something like £250 VAT for one, and when I had a look at the photographs, it didn't offer much in the way of protection. Problem being that when my Kubota was made there was no requirement for a roll bar type of safety device, and therefore no substantial supports or mounts for one where fitted.
In the end I had the local agricultural engineer (alright, Blacksmith or "Hugh the Gas" to those who know him) make me one. He did a great job and all it cost me was materials (£85 in steel, mainly off cuts) and an hour or two of PC support.
If you get stuck with Radiators for the Kubota (or similar) then I can recommend Wrexham Radiators. They fixed up a blown radiator for me, for £65, good as new. Saved me nearly £200 as opposed to buying a new one! I know they offer a postal service and are really helpful. Small Father & Son business.
I'll look up the Rust Bullet stuff and see how I get on.
Its getting a bit parky in the mountains, so I'll be on log lugging duties this weekend.
Bye for now
